Nickel Alloy Round Bar Inconel Alloy, Incoloy Round Bar / Hastelloy
Bars Custom Cutting into Any Length
Nickel alloy round bars represent a class of high-performance
metallic materials engineered to deliver exceptional reliability in
the most demanding industrial environments. Composed primarily of
nickel blended with elements like chromium, molybdenum, iron, and
copper, these round bars are manufactured through precision
processes including forging, rolling, and cold drawing to ensure
uniform structure and consistent performance. Available in
customizable diameters from 3.17mm to 350mm and with flexible
length options (standard 1m to 12m, plus custom cutting to any
specified length), they cater to diverse manufacturing needs across
industries requiring durability, corrosion resistance, and thermal
stability. Whether for large-scale industrial equipment or
precision components, our nickel alloy round bars—including
Inconel, Incoloy, and Hastelloy variants—meet stringent quality
benchmarks for critical applications.
Common Grades of Nickel Alloy Round Bars
Different nickel alloy grades are formulated to address specific
environmental and mechanical requirements. Below are the most
widely used grades and their core characteristics:
| Grade Category | Specific Grades | Key Composition & Traits |
|---|
| Pure Nickel | Nickel 200 (UNS N02200), Nickel 201 (UNS N02201) | 99%+ nickel content; exceptional corrosion resistance and thermal
conductivity. Nickel 201 offers lower carbon for improved
high-temperature performance. |
| Inconel | Inconel 600 (UNS N06600), Inconel 625 (UNS N06625), Inconel 718 | Nickel-chromium base; superior high-temperature strength (up to
1200°F) and oxidation resistance. Inconel 625 adds molybdenum for
enhanced corrosion resistance. |
| Incoloy | Incoloy 800 (UNS N08800), Incoloy 825 (UNS N08825) | Nickel-iron-chromium alloy; balanced corrosion resistance and
thermal stability. Ideal for sulfuric acid environments and thermal
cycling applications. |
| Hastelloy | Hastelloy C276 (UNS N10276), Hastelloy C22 | Nickel-molybdenum-chromium blend; universal corrosion resistance in
oxidizing/reducing acids, chlorides, and seawater. Resists pitting
and stress corrosion cracking. |
| Monel | Monel 400 (UNS N04400) | Nickel-copper alloy; high strength and marine corrosion resistance.
Used in saltwater and chemical processing environments. |
Industry Standards for Nickel Alloy Round Bars
Our nickel alloy round bars adhere to globally recognized standards
to ensure consistency, safety, and compatibility with international
manufacturing requirements:
- ASTM/ASME Standards: ASTM B160 (Nickel 200/201), ASTM B925 (general
nickel alloy bars), ASME SB160 (seamless nickel alloy bars) —
specify ,mechanical properties, and dimensional tolerances.
- Aerospace Specifications: AMS 5660 — sets rigorous standards for
purity, heat treatment, and non-destructive testing for
aerospace-grade applications.
- International Standards: DIN (Germany), JIS (Japan), BS (UK) —
align with regional manufacturing norms for surface quality (Ra ≤
1.6μm typical) and mechanical performance.
- Custom Certifications: Available with mill test reports (MTRs),
NACE MR0175 compliance (for oil/gas), and FDA approval (for food
processing) upon request.
Key Features of Nickel Alloy Round Bars
The superior performance of nickel alloy round bars stems from
their unique material properties, making them indispensable for
harsh-environment applications:
- Exceptional Corrosion Resistance: Nickel forms a dense,
self-healing oxide layer that protects against acids (sulfuric,
hydrochloric), alkalis, seawater, and chlorides. Hastelloy C276 and
Incoloy 825 excel in the most aggressive chemical environments.
- High-Temperature Stability: Retains strength and oxidation
resistance at extreme temperatures — Inconel 600 operates reliably
up to 1453°C, while Nickel 200 maintains performance from cryogenic
levels to 1200°F.
- Superior Mechanical Strength: High tensile strength (≥520MPa for
Nickel 200) and toughness enable resistance to heavy loads and
deformation. Forged variants offer enhanced structural integrity
for high-stress components.
- Excellent Fabricability: Easy to machine, weld, and form into
precision parts. Supports cold/hot working processes without
compromising corrosion resistance or strength.
- Long-Term Durability: Resists dimensional changes and material
fatigue, reducing maintenance costs and equipment downtime in
critical applications.
Applications Across Industries
Nickel alloy round bars are integral to industries where material
failure could lead to safety risks or operational disruption:
- Chemical Processing: Reactors, pipes, valves, and pump shafts —
Hastelloy C276 and Nickel 200 withstand corrosive feedstocks and
high-pressure reactions.
- Oil & Gas: Downhole tools, wellhead components, and offshore
platforms — Monel 400 and Inconel 718 resist sulfide stress
cracking and seawater corrosion.
- Aerospace & Defense: Turbine blades, engine components, and
spacecraft parts — Inconel 625 and 718 handle extreme heat and
mechanical stress.
- Marine Engineering: Ship propellers, offshore pipelines, and
desalination equipment — UNS N02201 and Monel 400 prevent
seawater-induced corrosion.
- Food & Pharmaceutical: Mixers, evaporators, and storage tanks —
Nickel 200’s non-toxic, corrosion-resistant properties ensure
compliance with food safety standards.
- Energy Sector: Nuclear control rods (Nickel 200), thermal power
plant heat exchangers (Incoloy 800), and renewable energy
components — withstands thermal cycling and aggressive coolants.
